Windows 7: BSoD Problems

I left the Memtest running last night. When I got back to the laptop there seemed to be quite a few errors. This is what was on the screen just before I stopped the test.

I don't know if that's helpful or not. I also had another BSoD the morning before I did the memtest, so I've attached a new zip file with the newest dump file.

The fact that Memtest shows errors indicates that you have a RAM problem. That problem can be one or more bad sticks of RAM, RAM sticks incompatible with each other, RAM incompatible with the motherboard, a bad RAM slot, or a bad memory controller. Remove all of your RAM sticks except the one in the first slot. Run Memtest on that stick. If it passes, remove it, mark it as good and test another stick in the same slot. Repeat until you have tested all of your sticks. If you find a bad stick, mark it as bad. Run your computer with just one RAM stick and see how it does.

Next take a known good stick and test each of your RAM slots with this stick. I know this is time consuming and tedious. If you find a bad slot, you will know not to use that slot. Post back with your results.

I did look at your dump and it is memory management error. It does not indicate any specific cause.

I tried the Driver Verifier again yesterday and it's working this time so I'm gonna let that run for 36 hours over the next couple of days and see if that can point to a bad driver.

In regards to the RAM, is the removal of RAM sticks an easy process? If it's a simple enough process, I'll give it a go after the Driver Verifier. I just don't want to mess up my laptop.

Also, I've just checked Acer's website and my laptop's BIOS isn't the latest version. Could that be what is causing the BSoDs?

Thanks for your help so far.

Be sure to upload any Verifier enabled dumps. If the dumps point to Windows system files, you can stop Verifier.

I am not familiar with your laptop. Many laptops have a door on the bottom that gives access to the memory without having to take the laptop apart. If your computer is still under warranty, you don't want to take it apart. And, if it is, I would let Acer deal with the RAM problem.

I don't lightly recommend flashing the BIOS. If not done correctly, it can turn you computer into a useless paper weight. There is a definite risk involved, albeit not a great risk. Generally, I recommend flashing the BIOS when the BIOS update addresses a specific problem that the computer is experiencing or when the manufacturer recommend the BIOS upgrade. Since I do not know what the latest addresses or corrects, I can't give you an answer. There are some BIOS updates that correct memory problems. Without all of the facts, I recommend that you solve the RAM problem first.

After 36 hours of the Driver Verifier no BSoD.

I think messing with the RAM may invalidate the warranty, so I'm gonna get Acer to look at the laptop next week.

Thanks again for all your help.

You are certainly welcome for the help. No BSOD's using Verifier is a good sign. It means Verifier found no faulty drivers. Good job of running it.

If there is a seal on the door that opens to the RAM, you definitely do not want to break it. If there is no seal, accessing the RAM probably does not invalidate the warranty. That said, as inconvenient as it may be, since the computer under warranty, I would let Acer handle it. I think you have made a good decision. Acer will also flash the BIOS if that is necessary. Please post back and update us after Acer looks at the RAM and tell us what they have done.
